摘　　要：20 0 1～ 2 0 0 4年对陕西省 181份小麦区试品种的成株期抗条锈性鉴定结果表明 ,区试品种对不同条锈菌流行小种的抗性存在明显差异。对条中 32号的抗性最差 ,抗病品种数为 4 8份 ,占区试品种的 35 .0 % ,其次为水源 11～14和条中 31号 ,抗病品种所占比例分别为 38.0 %和 4 5 .3% ,对条中 2 9号、30号、水源 11～ 13以及太白 4的抗性相对较好。调查其中 12 8份区试品种的自然发病情况表明 ,表现免疫 近免疫和高抗 中抗的品种分别占 7.0 %和 2 8.9% ,而中感 高感品种占 6 4 .1%。One hundred and eighty-one wheat varieties from Shaanxi province were identified for resistance to stripe rust during 2001～2004,the results showed that there were obvious difference in resistance to different prevalent races.The resistance to CY32 was worst,and the number of varieties was 48,which percentage was 35.0%. Next were Su11～14 and CY31,and the percentage of resistant varieties were 38.0% and 45.3%. The resistances to CY29、CY30、Su11～13、Taibai 4 were better than that of CY32、CY31 and Su11～14.In addition,investigating 128 varieties' nature disease, the proportion of immune or near immune varieties and high or middle resistant varieties were 7.0%、28.9%, and the percentage of middle or high susceptible varieties was 64.1%.
